To all whom it 1r'iay`coi'rc-er1i.:l l

Be it known that I, LYMAN S. Cno'rsnn, a citizen of the United States, residing at Petoskey, in the county of Emmet and State of Michigan, have invented certain new and useful Improvements in Rail-Fasteners, 0f which the following is a specification.

This invention relates to railway ties and refers particularly to an'iinproved fastening means for securing the rails thereto.

An object of this invention is to provide an improved key which is insertedvin a tie of concrete formation and which inay be readily detached therefrom when it is desired to remove the rail fastening bolts from tlie'tie, i

The invention has 'forinother object the provision ot an improved means for preventing the creepingr of the rails through the improved fastening means in oider to rigidly `r'et'aiii the same to the tie and to thereby.

torm a combined means for securing `the rails in Vrigid relation to the tie.

Iior a lull understanding of the-invention reference isto be had to the following deseri tion and accom an yinof'drawiiifrs in.

Figure 1 is a longitudinal section through the improved tie disclosing the fastening` means as secured to rails supported Hier'eon. Fig. 2 is a detailed longitudinal vSection through one end of the'tie'shoiving olie of the keysand securing bolts positioned iiithe securing plate. Fig. 3 is a detailed section through one of the keys employed. Fig. 4 is a detailed sectional view ot the improved vsecuring means for preventing the creeping ot' the rails, and Fig. 5 is'la detailed perspective view 'of one of the anti-Creepery blocks employed.

Corresponding and like parts are referred to in the following description and indi cated in all the views of thedrawing by the saine reference characters. u

Referring to the drawing theaiumeral 10 designates a body of concrete which forms a tie and which is i-ein't'orcedby the provision of the end plates 11. which su )port a plurality of longitudinally dispose wires 'ir tie rods 12 at the opposite corners of the plates. Interiiiediately of the plates cables 13 are positioned which extend inwardly and are engaged at their inner extremities to the outer ends of the securing plates 14 which are positioned inA vertical a iienient within ih\e body portion .10 of the tie.

inner end spf Vthe plates are supported by the provision of intermediate cables 15 which are stretched between the extremities f of the saine and serve to prevent the plates 1- t from longitudinal displacement. The plates lll are each provided with longitudinal slots 16 adjacent their oppositeends which are reduced at their inner ends for4 the reception of clamping bolts 17 which aie passed vertically through the plates 14 and provided with enlarged heads 1S at their lower extremities for engagement against the niider face of the lowermost ot' the plates 1t to prevent the forward movement of the clamping bolts 17 when the saine arc engaged in the reduced portions of the slots 16. The Aclamping bolts 17 ai'e retained in the reduced portions ot' the slots 1G by the )revision of split keys which are formed iii two sections, cach of which is provided with seinhcircular grooves 1*.) longitudinally foi-ined in the o iposite faces of the saine and adapted to register with eaeh other. -The grooves 1t) are threaded for the i'cception of a threaded vpin V2O which is positioned between the sections 21 and 22 of the split key for the 'purpose ot' splitting the saine and of wedging the key through the plates 14 and against the clamping bolts 17. The beveled 4tiices of the keys are formed upon the outer sections 22 so as to force the inner straight, ed eof the same against -the bolts .zlhe s it. keys are retained in lposition downward y within the tie by thel provision of rest plates 23 which are engaged transveisely upon the outer face of the tie and upon which the rails 24 are positioned. 'lhe rest plates 23 are apertured for the reception of the elampinv bolts 17 therethrough and are provided withtish )lates 25 which engage upon the opposite si es ofv i the rails 24 and are clampec thereagainst by means of suitable nuts 26 carried uponV the ueper extremities of the' clamping bolts 1 The means employed for preventing the creeping of the rails "24; comprises anti larged at theirV outer extremities thii'igh which the clamping bolts 17 are engaged in order to secure the same rigidly against the rails 24. The provision of the studs 28 forms 'shoulders u on the inner ends which bind against the sides of the web of the rail and retain the studs 28 in position when a longitudinal strain is exerted-upon the rail. In this construction it is referable to alternate the anti-Creeper bloc s 27 with the fish plates 25 or to'position the creeper blocks 23 atintervals of about six ties apart so as to form a substantial securing means for therails 24.

When it is desired to remove the clamping bolts 17 the rest plates 23 are raised frorr` is claimed as new is 1. A rail fastener including a'body of concrete, end plates embedded 1n the opposite extremities of said body, cables extended across the corners of said end plates straight through the body, securing plates positioned adjacent the ends of said body and in vertical alinement, said securing end plates being attached to said cables, said securing plates also having slots longitudinally formed adjacent the ends of the same, clamping bolts engaged through said securing plates and extended upwardly from the same, enlarged heads formed upon the lower extremities of said clamping bolts for engagement against the under face of said plates, key sections ositioned through said plates against said bolts, threaded pins engaged between said sections for expanding the same, the outer of said sections being of wedge formation to bind=eachofsaid bolts in osition, a rest plate engaged beneath the rail and over the upper ends of said pins, fish plates engaged upon said rest plates and against the opposite sides of the rail and nuts engaged upon the n per ends of said bolts for retaining said sh plates in position. .4'

2. A rail 'fastener including an elongated body of concrete, airs of securing plates embedded in said ody adjacent the ends thereof, clam ing bolts engaged through said plates an extended upwardly from the same, enlarged heads formed upon said bolts for engagement against the under faces of the lower of said plates, key sections positioned through said plates against said bolts, threaded pins disposed between said sections for expanding the same, the outer of said sections being of wedge formation to retain said bolts in position, rest plates carried by said body and engaged over said key see tions, said restplates having recesses therein to receive the heads of said pins, and means carried b said bolts for -retaining rails across sai body.

3. In a rail fastener the combination with an elongatedv body of concrete, of end plates embedded in the ends of said body, securing plates arranged in said body adjacent the ends thereof, cablesextended between said securing plates and between said end plates, bolts u wardly extended through said securing p ates, split keys carried by said securing plates against said bolts, pins disposed through said ke s and having the heads thereof terminated7 upon the upper face of said body, rest plates disposed over saidpins and having recesses formed in the under faces thereof for the reception of the heads, said bolts extending upwardly beyond said rest plates, fish plates 4carried by said bolts for engagement with a rail and clamping nuts positioned upon said bolts for securing said fish plates in position.

In testimon whereof I atiix my signature inv presence o two witnesses.
